  • EP-A-1,022,635 discloses a cartridge according to the preamble of claim 1.
  • thermostatic cartridges of this type with a single-lever control are known, making it possible to constitute "mixer” taps, ie by means of which the flow and temperature settings are made by actuating a single lever.
  • These cartridges provide flow control by means of two superimposed ceramic disks, the lower disk having up and down channels for the cold fluid and the hot inlet fluid, and the temperature control of the mixed output fluid at the outlet. by means of a temperature control slide located downstream, below the lower disk, secured to a thermostatic control element.
  • thermostatic cartridges of this type with concentric controls, requiring a valve having two concentric handles for controlling the flow and temperature.
  • the flow control is also provided by two ceramic disks, and the temperature adjustment by a temperature control slide fastened to a thermostatic element, but the two disks have cold fluid rise channels and hot fluid, and the drawer, located downstream of these channels, is this time disposed above the upper disk.
  • the arrangement of the cartridge limits the available diameter for the temperature control spool and the fluid passage section, resulting in poor temperature regulation, which is incompatible with the standards in force for thermostatic valves. , and low throughput, which limits the range of possible applications.
  • the object of the invention is to remedy these drawbacks and concerns for this purpose a thermostatic cartridge with ceramic disks for a fluid valve, of the quarter-turn type with concentric controls, comprising a regulating slide secured to a moving part of a thermostatic element, and first and second flow control discs contiguous to one of their faces, characterized in that the first disc has two internal through passages of hot fluid extending approximately into arcs of circumferences of approximately equal radii , separated and approximately end-to-end, two through-passages of cold fluid extending approximately into arcs of circumferences of approximately equal radius, separated and approximately end to end, and an internal recess opening into the face of the disk which is not attached to the second disc and whose bottom is a seat for the drawer and is in communicating with one of the cold fluid passages, and the second disk has two internal passages respectively of hot fluid and cold fluid extending approximately in arcs circumferences and is rotatable relative to the first disk from a position of opening wherein the hot fluid passage of the second disk connect

  • the hot and cold water begin to mix, and mixing continues around the thermostatic element 5 and in particular its heat-sensitive region and inside the turbulator 14 inserted into the 1D mixed water outlet duct through which the mixed water is discharged.
  • the flow rate adjustment is obtained by a rotation of the flow control lever 4, causing a rotation of the upper disc 3 defining the angular position of this disc relative to the lower disc 2, and thus the flow section for the water hot resulting from the more or less extensive superposition of the passage 3A of the upper disc and the second passage 2C of the lower disc, and the flow section for the cold water resulting from the more or less extensive superposition of the passage 3B of the upper disc and the second 2D passage of the lower disk.
  • the shapes of the passages are adapted so that the flow sections of hot water and cold water are equal regardless of the relative angular position between the two discs.
  • the flow sections vary from total closure to maximum opening, and vice versa.
  • the thermostatic element 5 When the temperature of the mixed water increases, the thermostatic element 5 is lengthened, the regulating slide 6 which is connected to it reduces the space which separates it from its seat 1F in the base of the casing 1 and increases that which separates it from its seat 2F in the lower disc 2, which decreases the flow section of the hot water and increases the flow section of the cold water; this results in a decrease in the temperature of the mixed water; the operation is reversed when the temperature of the mixed water decreases. Corrections of the water temperature mixed by the thermostatic element equilibrate until the stabilization of this temperature to a value that depends on the altitude at which the piston (normally fixed portion) of the thermostatic element 5 culminates.
  • the adjustment of the temperature is obtained by the rotation of the temperature control lever 7 which, by the screw-nut system, imparts a translational movement to the temperature adjustment screw 10 which causes the overtravel support 11 (both that the regulation slide 6 is not in abutment against the upper disk 3) against which the piston of the thermostatic element 5 is supported.
  • a stop device internal to the cartridge (stop of the temperature adjustment screw 10 on the temperature control lever 7) or external (wheel adapted to the handle 7) limits the adjustment temperature to an appropriate value (for example 50 ° C or 55 ° C maximum at the "draw" point).
  • the cartridge of FIG. 7 comprises an upper disc 3 whose hot water passage 3A and the cold water passage 3B are not traversing from one of its faces to the other, and a control lever of flow 4 whose flange of the lower part 4A does not have, unlike the previous case, a hot water chamber or cold water chamber and can be reduced itself to a simple disk attached to the upper face of the upper disk 3.
  • the operation is identical to that of the first embodiment, except that the hot water and the cold water circulate only in the passages 3A, 3B of the upper disc 3 before descending through the lower disc 2. This results in a simpler parts manufacture and assembly than for the first embodiment.
